Nokia unveiled the Lumia 900, its first 4G LTE phone.
Nokia CEO Stephen Elop introduced the Windows Phone 7.5 Mango device at a press conference at CES, where he was joined by Microsoft CEO Steve Ballmer. The Lumia 900 will follow Nokia's first Windows Phone, the Lumia 710.
"We have a lot of room to go in terms of selling Windows phones," Ballmer said, but he noted that AT&T is already the biggest Windows Phone carrier in the US Windows Phone has less than 3% of the smartphone market, well behind Apple's iPhone and various Android devices.
AT&T Mobility's CEO Ralph de la Vega joined Elop and Ballmer. "Believe me, I think Nokia is going to be back in the US in a very big way," de la Vega said. "This phone is truly built around people and not applications."
The Lumia will ship in coming weeks, he said.
Nokia emphassed high quality front and rear-facing cameras in the Lumia 900, but otherwise discussed few details.
Prior to the announcement, various blogs said the phone would have a 4.3-inch screen and one 8-megapixel camera. The phone has a 1.4 GHz Snapdragon processor, an 1830 mAh battery and 16GB of internal storage.
Pricing for the Lumia 900 was not disclosed.
